Apps ask before they use your camera, microphone or location. Google connectors are in testing (Calendar) or planned (Gmail, Drive).

He reaches out firstAvailable now

Tell it once. It shows up when it matters.

Connect your servicesIn testingPlanned

Bring your digital life into one conversation.

Your schedule, your inbox, your tasks and your files, through the AI that already knows your context. Calendar is in testing; mail, tasks and files are planned.

The reminders he sets are available now. Each service connects only when you choose to.

ResearchPlanned

Ask it to find out.

Give Zetro a question that needs digging. He looks into it and comes back with something organised you can act on, and can turn it into an app of its own.

Beyond youIn testing

Your world grows.

Your AI can meet other people’s AIs to find people you’d get on with, and the apps people build with Zetro can be shared, so anyone can get their own private copy.

Wingman

Tell it who you’d like to meet. It talks with the Wingmen of people who chose to be found, using only what each person shared. Nobody is introduced unless both say yes.

Marketplace

Browse apps other people made with Zetro and get your own copy. Whatever you put in your copy stays private.

Privacy and controlAvailable now

Yours, and only yours.

A friend who knows you has to be one you can trust. You can see what Zetro knows, change it, and take it all back.

  • See everything he remembers, then correct it, forget it, or switch automatic memory off.
  • Decide when he texts with quiet hours, or ask him to stop texting first.
  • Apps ask first before they use your camera, microphone or location.
  • Download or delete everything from inside the app, on every phone at once.
  • No ads and no ad trackers in the app.
  • Plain about the AI: your messages are sent to Anthropic’s AI models so Zetro can reply.

Questions

More in Support, or write to support@zetro1.com.

Is Zetro a real person?
No. Zetro is an AI. His personality, feelings and the life he talks about are written by AI models, and the app says so.
What kinds of apps can he make?
Trackers, planners, logs, lists, journals, small games and tools, built from parts like forms, lists, charts, photos, maps, reminders and AI help. When an idea needs something he can’t do yet, he tells you.
Which services can he connect to?
Google Calendar is in testing. Mail, tasks and files are planned. Each one connects only if you choose to.
What does Zetro remember?
The people, plans and preferences you mention. You can see all of it in What Zetro remembers, correct it, forget it or turn memory off.
Is Zetro a therapist?
No. He’s a friend to talk to, not a doctor or a crisis line. In an emergency, call 911 in the US and Canada or 999 in the UK.
When can I get Zetro One?
It’s coming to Google Play and the App Store.
